In the title compound, C(12)H(12)NS(+)·C(7)H(7)O(3)S(-), the cation exists in an E configuration with respect to the ethenyl C=C bond. The cation is essentially planar with a dihedral angle of 1.94 (10)° between the pyridinium and thio-phene rings. The benzene ring of the anion makes dihedral angles of 75.23 (10) and 76.83 (10)°, respectively, with the pyridinium and thio-phene rings. In the crystal structure, cations and anions form alternate layers parallel to the bc plane. Within each layer, both cations and anions are arranged into chains directed along the b axis. The cation chain and the anion chain are inter-connected by weak C-H⋯O inter-actions into a three-dimensional network. The crystal structure is further stabilized by C-H⋯π inter-actions.
在标题化合物C₁₂H₁₂NS⁺·C₇H₇O₃S⁻中,阳离子相对于乙烯基C=C键呈E构型。阳离子基本呈平面状,吡啶鎓环与噻吩环之间的二面角为1.94 (10)°。阴离子的苯环与吡啶鎓环和噻吩环的二面角分别为75.23 (10)°和76.83 (10)°。在晶体结构中,阳离子和阴离子形成平行于bc平面的交替层。在每层内,阳离子和阴离子都排列成沿b轴方向的链。阳离子链和阴离子链通过弱C-H⋯O相互作用相互连接成三维网络。晶体结构通过C-H⋯π相互作用进一步稳定。
